MINECRAFT - Win $100k by solving my problem!

[ORIGINALLY POSTED ON MINECRAFT FORUM]

Hello everyone,

I'm a newly register on this forum. I'd like to share my problem with minecraft and I'd like some support if available and possible.

However I got a free minecraft account by a gift code that was given to me by my best pal. I got it in the early 2011. I bought about 3 new computers, I'm using the 3rd one. Everything worked a couple of months back, normally. However now I get this error now: "classnotfoundexception net.minecraft.launcher". I rarely go register on forums and fill these in, because I usually find a solution on google.com. I had loads of problems such as with java, opengl, graphics card, I got through them easily. But this, eh, I just can't figure out.

Okay so, when I open the browser, go to: "www.minecraft.net", log in and when I click the link to the "/play", I go to the game loading page. I see this: "Error. Click for details" with red letters. Then I see this;

"classnotfoundexception net.minecraft.launcher", then it says "details", so I go onto that and see this:

Java Plug-in 10.7.2.11
Using JRE version 1.7.0_07-b11 Java HotSpotâ„¢ Client VM

s:   dump system and deployment properties
t:   dump thread list
v:   dump thread stack
x:   clear classloader cache
0-5: set trace level to <n>
----------------------------------------------------

Just that.

I've tried; Reinstalling java, installing java 6 & 7 version, deleted the .minecraft in the applications folder and now I cannot download it back. However before I deleted the .minecraft, I could of played only in singleplayer and on the "minecraft.exe" client. I have WINDOWS XP Pro. I can't login aswell on the client, however I can log into the website of minecraft.

I have no idea what to try anymore, can anyone please post their suggestions or something? I'd VERY MUCH appreciate. I really miss minecraft, I even tho gave away loads of stuff on other multiplayer games just to find a solution for me.

Yours sincerely forever,
Starky/Zlatan/Technohopper, etc.

Have you tried downloading the actual game?
http://minecraft.net/download

Delete minecraft, download it from the above link and allow it to install and update itself.

One of those MUST work! Try the following:

Solution A:
Remove the latest Java version you have and install Java Version 6 Update 32. Make sure you find a version that is Windows XP and 32 Bit. Minecraft should work now, just by running minecraft.exe.

Solution A+:
Delete the entire ".technicPack" folder and the entire ".minecraft" folder from %appdata%.
Then remove all versions of java you have installed and re-install Java.

Solution B:
Update your Graphic card driver.

Solution C:
When you are about to log in hit options then hit force update then log in.

Solution D:
There are two minecraft.jar files. The pre-release minecraft.jar is the game itself and needs to be placed in ~/.minecraft/bin
The second minecraft.jar is the launcher file that is downloaded from minecraft.net. Try to move it to ~/bin.
